RAILWAY APPLIANCE.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed February 4, 1907. Serial N0. 355,6 26- To all 'wh/07M,t 11i/wy concern.-

Be it known that I, LUDWIG LIPTAI, a subject of the King ofAustria-Hungary, and a resident of the city of New York, in the countyOf New York and State of New York, have invented certain new and usefulImprovements in Railway Appliances, Of which the following is aspecification.

The invention relates to railway appliances and its Object is to deviatethe impact of a collision from a rectangular direction to one Of anacute angle, so that the danger Of destruction to railroad stock and tolife Of the passengers is considerably diminished.

The drawings illustrate in Figure 1 a side elevation Of the end of acar, in Fig. 2 a horizontal cross-section of the same, in Fig. 3 a topview Of the other end of the car, in Fig. 4 an end view of the same, inFig. 5 a detail of construction, and in Fig. 6 a diagram of a number ofcars.

The body Of the car is indicated at 1, and the usual platforms 2 areOrganized-to carry an inclined frame 3, having supporting beams 4,slidable in brackets 5 of the platform. Between the frame and theplatform are springs 6 for taking up part of the impact of concussion.It will be seen that the platform, as well as the frame 3, are at anacute angle to the longitudinal axis of the car. The frame 3 is providedwith a number of rollers 7, preferably cone-shaped, and made oflengthwise corrugated material. The rollers are supported in the frameby means of Ournals 8, and each roller carries an arm 9, capable ofacting upon a crank 10, Or similar device, supported in a bearing 11 Ofthe truck, the other end of the crank or shaft being formed according tothe result to be accomplished by operating it, for instance as themovable part of an electric contact. The purpose Of this device is todisconnect, whenever rotation is im arted to either of the rollers 7,mechanica devices, such as brakes or valves, or electrical devices, suchas contacts, so that the power is shut olf Of the train and the brakesapplied to the wheels.

cated at the frontand rear-end of each train,

and in case of collision between two trains, running On the s ame track,the frames will obviously be the first members to meet, and one of thesaine glides up unto the other, causing, by contact with the rollers ofthe other train, rotation Of its own rollers aswell as of the rollers ofthe other train. The levers on the rollers will coact with the devicescontrolling the power and the brakes of the train, and by shutting Offthe power and applying thebrakes, the cars or the trains are brought tOstandstill.

It is obvious that a collision at right angles to the front or rear endof the car of a train will cause the utmost destruction. rI`he inventionillustrated in Fig. 6, showing lthe front and rear ends of the carsformed at an angle diiierent from a right angle to the axis Of a train,causes, in case Of a collision, a gliding Off of the individual cars,and the diminution of the imp act, which is facilitated by a frame 16 Oneach end Of the cars, provided with a series Of vertical rollers 17,which may be used for similar purposes as the rollers 7. i

As new and useful is claimed and desired tO be secured by Letters Patentof the United States 1.. In a railway appliance, the combination with acar having powerand brake-controlling devices and its ends formed atangles different from right angles to the axis of the car, of a frame ateach end Of the car, a plurality Of rollers in said frame, and meanscontrolled by said rollers and adapted to Operate said powerandbrake-controlling devices.

2. In a railway appliance, the combination with a car having its endsformed at an angle different from right angles tO the axis of the car, aframe at each end of the car, a plurality of rollers in said frame andadapted to coact with the corresponding rollers of an adjoining car.

Signed at New York, in the county of New York, and State of New York,this second The modification, illustrated in Fig. 5, i day Of February,A. D. 1907.

comprises a shield 13, slidably fastened to the frame 3 by means of abar 14 and controlled by springs 15, located between the end of theframe and the shield.
